FTTx stimulates tri-speed Ethernet standard

摘要

A major reason for Ethernet's unparalleled success in customer-owned networks has been support of higher speeds as network traffic increases. Extending the performance of the original 10-Mbit/sec Ethernet are 100-Mbit/sec Fast Ethernet (FE), Gigabit Ethernet (GbE), and 10-GbE. 100-Mbit/sec FE as originally introduced for unshielded twisted-pair copper was not backward-compatible with 10-Mbit/sec Ethernt. Today copper Ethernet products support 10, 100 and 1, 000 Mbits/sec, enabling smooth migration paths.
